Grammy Award-winning performer Usher steps onto the treadmill of the Off-Broadway spectacle Fuerza Bruta for two special performances April 28 at the Daryl Roth Theatre.

The interactive staging, which has the audience moving throughout a shifting environment where performers run high overhead in a visual fantasy that includes a suspended, mylar pool, began performances Oct. 11, 2007, and opened Oct. 24 at the former home of De La Guarda.

Usher, who has also been seen on Broadway as Billy Flynn in Chicago, takes on the lead role of "Running Man" in Fuerza Bruta's opening and closing sequences for the 7 PM and 10 PM performances.

De La Guarda's Diqui James (co-founder/co-creator) and Gaby Kerpel (composer/musical director) created Fuerza Bruta. S2BN Entertainment produces the New York run.

Tickets, priced $150, are on sale for Usher's special performances. VIP packages, including a Fuerza Bruta T-shirt, a special edition program signed by Usher and a digital download of his upcoming album "Looking For Myself," are available for $200.

According to press notes, "Breaking free from the confines of spoken language and theatrical convention, Fuerza Bruta is an event where worlds collide and reality takes a back seat. At show time, audiences are ushered onto the main stage where they are engulfed in a 360 degree spectacle featuring mind-blowing visual effects just inches above the audience that must be seen to be believed - a man running full throttle on a giant treadmill, bursting through a series of moving walls; performers suspended in mid-air surrounded by a vast sea of mylar; and gorgeous women twisting ethereally in a lucite pool above the audience."

Tickets to Fuerza Bruta at the Daryl Roth Theatre, 20 Union Square East (at 15th Street), can be purchased by calling (212) 239-6200 or at the box office. Visit Telecharge.com.
